“Marty Kihn did leave Gartner and accepted an opportunity with Dentsu Aegis,” a Gartner spokesperson said in an email to AdExchanger. “We will be backfilling Marty’s position in addition to filling other open headcount in data and analytics, mar tech and advertising, so you’ll be seeing thought leadership from some new talent soon.”

Kihn was recognized at Gartner for his extensive research of ad tech, especially data management platforms, and other marketing technology. He has been the face of Gartner’s research division for the past five years.
